Cyperus
(Papyrus)
|
|
The family Cyperaceae
is a large group of grasslike herbaceous plants that includes 70 genera
and about 4000 species usually found in wetlands. The genus for which
the family is named is Cyperus, (pronounced sy PEAR us)
and several of the species in that genus are commonly known as Papyrus
(pa PIE rus). These plants are mainly found in tropical and subtropical
areas of Africa, Asia, and South America, with just a few species in temperate
regions. Where they are not hardy, which is most of the US, they make
excellent houseplants and pond plants that are overwintered indoors.

Cyperus
alternifolius,
sometimes
called Umbrella Plant, is an old-fashioned houseplant that is
due for a revival. Its tall, upright habit is very dramatic in a narrow
space and, although naturally a water plant, requires only moderate
watering indoors. The terminal umbrella of narrow leaves is adorned
with flowers and seed heads from time to time, and although these are
not colorful, they are attractive. This plant will grow to 5' or more,
given a large enough pot and ample water and fertilizer, but can be
kept smaller if desired. Zone 9.

Cyperus
alternifolius gracilis, Sparkler
Grass, is like the above, but much smaller, growing to about 18",
and with narrower leaves and stems. It's a nice pond plant that is less
overwhelming than its larger cousin, and good paired with the similarly-sized
C. haspan, below. Zone 9.

Cyperus
haspan is
called Pygmy Egyptian Papyrus. It's form is similar to the giant
C. papyrus, except that its leaves don't droop. It grows to about
18" and is the perfect companion to C. alternifolius gracilis,
above. Zone 9.

Cyperus
diffusus is
sometimes called Dwarf Papyrus, though that could refer to other
plants as well. It is a rather squat plant, to about a foot tall, with
leaves that are broader even than C. alternifolius. This species
seems not so fond of water as the others, but it is vigorous in a moist
situation. It is very apt to flower in the unspectacular but attractive
manner of Cyperus, and is a good companion to its variegated version,
below. Zone 10

|
Cyperus
diffusus variegatus is a very pretty variegated form that has
such light green foliage that it can appear white. It shares the predisposition
to flower with its green cousin above, its broad leaves, and some, but
not all, of that plant's vigor. Zone 10
